Application led October 25, 1918. Serial No, 259,730.

To all 'whom it may concern:

Be it known that I, FERDINAND Noirm- LICH, a citizen of the United States of America, and resident of Ute, Monona county, Iowa, have invented certain Improvements in Dumping-Carriages, of which the following is a specification.

The object of this invention is to provide an improved construction for a carriage adapted to receive, convey and deposit material such as earth from an excavation.

A further object of this invention is to provide an improved construction for means to retain a dumping-bottom in closed position so as to retain and convey material in a carriage.

A further object of this invention is to provide improved means for opening or releasing a dumping-bottom in a carriage, said means being adapted for manual actuation or for tripping operation by means Carried by a track over which the carriage travels.

A further object of this invention is to provide improved means for setting or adjusting the bottom to closed position and setting the retaining devices relative thereto.

A further object of this invention is to provide improved means for preventing leakage of material, such as earth, from the bottom of a dumping carriage.

A further object of this invention is to provide improved means for locking the steering-truck of a dumping carriage for travel of said carriage on a track in a right line.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a plan, Fig. 2 a bottom plan, Fig. 3 a side elevation and Fig. 4 a rear end elevation of a carriage embodying my invention, the wheels being omitted from Figs. 1, 2 and4. Fig. y5 is a detail side elevation of the rear portion of the carriage, the dumping devices and bottom being shown in open or dumped position. Fig. 6 is a cross-section on an enlarged scale, on the indicated line 6-6 of Fig. 2. Fig. 7 is a detail plan of a tongue or bail adapted to be employed on drawing the carriage. y

The device herein shown and described may be employed in connection with the elevating mechanism illustrated, described and claimed in my companion application filed October 25, 1918, Serial Number 259,729; although its use is not limited to such associated use.

In the construction of the device as shown a box is employed, comprising side walls 10, 11, end walls 12, 13, and a center-bar 14 rigidly connected, the bottom face of the centerbar being Hush with the lower margins of the side-walls; together with dumping leaves or boards 15, 16 fitted between said walls and center-bar and hinged to the side walls, thus forming a bottom for the box. Aprons 17, 18 are xed to the side and end walls respectively and a triangular apron 19 is fixed to the center-bar, said aprons preferably being made of sheet metal and arranged to overlap the joints or cracks formed by the margins of the bottom boards or leaves 15, 16 to prevent leakage of material from the box. Arms 20, 21 are fixed to the bottom faces of the boards or leaves 15, 16 and extend across and at right angles to the inner margins of said boards in overlapping relation with the center-bar 14. A groove is formed in and longitudinally of the bottom of the centerbar 14 and a locking-bar 22 is slidingly mounted in said groove, and is conned therein by clips 24 laid across the lockingbar and fixed to the center-bar. Plates 25 are fixed to the locking-bar 22 and project laterally therefrom and are adapted to over` lap and confine the inner ends of the arms 20,21 and hold the leaves or boards 15, 16 in closed position (Fig. 6). An anchor 26 is fixed at one end to the forward portion of the bottom of the box and inclines downwardly and rearwardly therefrom and a retractile coil spring 27 is attached at one end to the lower rear end of said anchor, extends across the forward clips 24 and plate 25 and is attached at its rear end to the locking-bar 22. It is the function of the spring 27 to draw and hold the locking-bar 22 forwardly with the plates 215 in positions to lock the arms 20, 21 and boards 15, 16 in closed positions. The locking-bar 22 is turned downwardly at its rear end to form a hook or handle 28 adapted for manual engagement to move the locking-bar rearwardly against the pull of the spring 27 to release the arms 20, 21 from the plates 25 and permit the leaves or boards 15, 16 to fall into open positions (Fig. 5). The hook or handle 28 also is adapted to engage a stop (as shown in my companion application4 above referred to) and, in the further travel of the carriage,

v tion.

effect the same relative movement of the locking-bar. An angle plate 29 is fixed to and projects upwardly from the rear end portion of the locking-bar 22, opposite the hook or handle 2S, and the upwardly-projecting portion of said plate inclines rearwardly. A lever 30 is fulcrumed between its ends on the rear end portion of the carriage and an expansive coil spring 31 is interposed between the upper portion of said lever and the rear end wall 13 of the box and tends to hold the lever in a given posi The lower end of the lever 30 is adapted to pass over and engage the angle plate 29 when the locking-bar 22 is moved rearwardly to opening position and hold said locking-bar during the dumping operation. Lifting' arms 32, 33 are fixed to and extend rearwardly from the leaves or boards 15, 16 adjacent to the center-bar 14 and a closing lever or handle 34 is fulcrumed at one end to a bracket 35 lixed to and extending rearwardly from the upper portion of the rear wall 13 of the box and inclines downwardly and rearwardly from said bracket. Chains 36, 37 are fixed to central portions of the lever 34 at one end and the opposite ends of said chains are attached by coil springs 38, 39 to rear ends of the lifting arms 32, 33. A hook 40 is formed on the upper end of the lever 30 and extends across the bracket 35 and said hook is adapted to be engaged by the closing lever 34 at times to oscillate the lever 30 and release the engagement thereof with the angle plate 29 so that the locking-bar 22 may be returned to closing position by the spring 27. Bolsters or sand-boards 41, 42 are fixed to and extend across and beneath the box at the front and rear ends thereof respectively, and arcuate bars'43, 44 are fixed at their inner upper ends to the bolster 42 and curve downwardly and laterally in opposite manner therefrom and terminate in hooks 45. The lifting arms 32, 33 are offset between their ends to clear the bolster 42 and said arms are adapted to move through arcs to and from open and Closed positions with their offset portions in contact, slidingly, with the arcuate bars 43, 44. The lifting arms are adapted to engage and be stopped in open position by the hooks 45 on the arcuate bars. An axle 4G is piv oted by a king-bolt 47 to the bolster 41 and is provided with wheels 48, one of which is shown in Fig. 3. A hook 49 is pivoted at its rear end to the side wall 11 of the box and is adapted to engage at times with an eye 50 projecting rearwardly from one end portion of the axle 46; said hook being adapted to engage at'times and be held in inoperative position by an eye 51 on said wall. When in the irst position the hook 49 locks the axle 46 against rotation on the king-bolt 47 and holds the carriage to a straight or right line of travel, as is indicated when said carriage is used on a structure such as is defined in my companion application. The rear bolster 42 is provided' with an axle 52 fixed thereto and furnished with wheels 53, one of which is shown lin Fig. 3. A handle, tongue or bail 54 is pivoted to the axle 46 and is adapted to be attached to draft means, such as the cable shown in my companion application, for drawing the carriage as desired.

In practical use the leaves or boards 15, 16 are locked in closed position and the box is loaded with material and drawn to a place of deposit of such material. The hook 28, preferably, is caused to engage a stop so located and arranged as to hold the lockingbar 22 while the carriage travels a sufficient distance to release the arms 20, 21 from the plates 25, whereupon the lever 30 passes over and engages the angle plate 29 to prevent accidental return of the locking-bar to locling position and the leaves or boards 15, 16 fall to open position and are limited in such movement by engagement of the arms 32, 33 with the hooks 45. The carriage then is stopped, such as by engagement with extra neous elements as dei-ined in my companion application; the dumping leaves or boards 15, 1G are raised by manually moving the lifting lever 34- upwardly through an arc, thus applying lifting force to the arms 32, 33 through the chains 36, 37 and springs 38, 39, said springs applying yielding strain; and, when the lever 34 reaches an upright position it is moved forwardly and contacts with and moves forwardly the upper end of the lever 30, thus causing the lower end of said lever to release the angle plate 29 and permit the locking-bar 22 to be moved for wardly by the spring 27 and place the Plates 25 beneath and in retaining relations with the arms 20, 21. Then Jthe lever 34-is permitted to fall into inoperative position, the lever 30 reassuming a position to engage the angle plate 29 on the next dumping operation of the carriage.

I do not desire to be limited to the precise construction and arrangement of parts, as the same may be altered in many particulars within the scope of the appended claims without departing from my invention.
